Ground granulated blast-furnace slag - Wikipedia
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in calcium silicate hydrates (CSH) which is
Blast Furnace Slag Cement - Manufacture, Properties and,
Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.
Ground Granulated Blast Furnace Slag - an overview,
Slag. Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the,
How Cement Is Made - Portland Cement Association
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.
What is slag cement
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield,
Portland cement - Wikipedia
Portland cement, blast furnace slag or fly ash and pozzolana * Constituents that are permitted in portland-composite cements are artificial pozzolans (blast furnace slag (in fact a latent hydraulic binder), silica fume, and fly ashes), or natural pozzolans (siliceous or siliceous aluminous materials such as volcanic ash glasses, calcined clays,
Portland Cement - an overview | ScienceDirect Topics
Portland cement consists of cement clinker and various other constituents, which determine its classification. These additional constituents can be granulated blast furnace slag, natural and industrial pozzolanic materials, burnt shale, limestone, silica fume, and calcium sulfate, which are added during the manufacture to control setting.
PORTLAND CEMENT
Portland cement is the basic ingredient of concrete. Concrete, one of the most widely used construction materials in the world, is formed when portland cement creates a paste with water that binds with sand and rock to harden. The U.S. industry average portland cement, as found by this study, is 91.4% clinker by weight. Table 1 describes the
